Why does my MCUK smell?

Your MCUK shouldn’t normally have a strong odor. The most common reasons for a menstrual cup developing an odor are:
- leaving the cup in a lot longer than the advised 4 to 8 hours; or
- boiling the cup in a saucepan that may have had traces of food left on the surface.
If this is not the case, you may have a non-serious vaginal infection that should be checked out by your doctor or nurse.
Removing odor from your MCUK
To remove the odor:
- Soak your menstrual cup in a small container of sterilizing solution such as that used for sterilizing baby bottle teats diluted to the manufacturer’s guidelines for the minimum recommended time (usually 7 to 10 minutes).
- Rinse thoroughly with clean water.
